摘要：
A technique employing the use of parallel feeds is applied to the recently proposed L-probe coupled patch antenna design. By employing only two L-probes, with Proper separation, for feeding one single patchy a twin-L-pro. be coupled patch antenna is designed with both high-gain (10 dBi) and wide-band [25%, standing wave radio (SWR) less than or equal to 1.5] characteristics. In addition, the 1-dB-gain bandwidth is around 26%, which covers the impedance bandwidth. Furthermore, a noticeable suppression of cross-polarization radiation is observed. Simulation results are in good agreement with those noteworthy characteristics obtained from experiments. The proposed antenna is suitable for modern mobile communication applications.
